Well damn, I'm trying to help the OP but I'm not doing very well so I need some help even if this is a little embarrassing.
WAIT....excuses first. I haven't worked on a VS front end in over 10 years. I've been focused on the street version. When I dissembled rollers....I figured " I'll never forget what this came off of" and a little of "Well they're pretty much all the same". So I didn't label most of my spare front ends.
Now I need to ID a VS front end and hopefully a 1968 if there happens to be any difference.
Pretending to know the isn't going to help. I don't really have time to research it either. I know there's folks on here that KNOW so I'm asking for help.
This looks VS to me but I can't even guess what year. ( these are damper rod)
Thanks in advance for the help, Gordon in NC
PS......if it helps the fender brackets are the cast/braze type ( heavy duty?)
